The answer is B, 4/-9 = 2/-3
A) In 1st Figure, Blue boxes means unit of diet soda = 8
Green boxed is regular sods = 4
Total Boxes = 12
Value of 1 Box = 888/12 = 74
Now, We know, we have 74 soda in each box, and 8 boxes of diet soda, so the number of diet soda = 74 * 8 = 592
In short, Your Answer would be: 592B.) Now, In 2nd figure, You can see
Red boxes mean Short sleeve short which is = 3
Green means Long sleeve = 7
Total Boxes = 10
Value of 1 Box = 460/10 = 46
Now, we know we have 46 shirts in each boxes and their is 3 boxes of short sleeves.
So, Number of Short sleeves = 46 * 3 = 138
In short, Your Answer would be: 138Hope this helps!

Step-by-step explanation:
I like to work problems involving repetitive calculations using a spreadsheet. The sort function can easily put the results in the appropriate order.
__
Here, we need to compute minutes and kilometers remaining for each cyclist, and then divide the former by the latter to find the required timing.
Minutes remaining will be the difference between the qualifying time and the time used so far.
Km remaining will be the difference between the race length and the distance traveled so far.
Required minutes per km will be the ratio of minutes remaining to km remaining.
Levi has the least allowed minutes per km for his remaining distance. Roberto has the most.
_____
Christopher only has to increase his average speed by about 5% in order to qualify; Levi has the greatest challenge, as he needs about 18% more speed for the rest of the race.
Because of the relatively large coefficients {9, 42, 49}, applying the quadratic formula would be a bit messy. Instead, I've chosen to "complete the square:"
9x^2 + 42x + 49 = 0 can be re-written as 9 [ x^2 + (42/9)x ] = -49
Dividing both sides by 9, we get [ x^2 + (42/9)x ] = - 49/9
Completing the square: [ x^2 + (42/9)x + (21/9)^2 - (21/9)^2 ] = -49/9
[ x + 21/9 ]^2 = 441/81 - 441/81 = 0
Then [ x + 21/9 ] = 0, and x = -21/9 (this is a double root).
